Nightlinger was published by Gauntlet in 1993.

Nightlinger chronicles the adventures of Nightlinger and Mike, his gorgeous Gal Friday. They operate out of a mysterious place called the Haunted Bookshop, and they investigate the paranormal. If supernatural forces, ghosts, zombies, vampires, etc., are plaguing you, someone may hand you a card from the Haunted Bookshop and let you know that their problems were solved by the card. You see, Nightlinger and Mike know that mankind's encounters with the paranormal are not isolated; they are manifestations of the never-ending battle between the forces of light and darkness a battle that could be lost in a heartbeat if our heroes ever look the other way.
